Data Migration from OpenText Content Server to Azure Blob Storage or other services.

Hi all

We want to migrate data (~40Terabyte) from OpenText Content Server to Azure Blog Storage or other similar/better services if any with a view to Archive (Closed Projects) about 80% of the data and other 20% (Active Projects) will be moved to SharePoint Online for business users to be able to access the data.

Another business requirement is to be able to search data in Azure Blob Storage effectively & efficiently via Azure Cognitive Services or other similar/better services.

I'd greatly appreciate any help or guidance or lessons learnt from anyone out there who have done similar migration of data from OpenText Content Server to Azure Blob Storage with any experiences to share.

It would be great to hear what techniques were used and how successful were you in migrating the data and what reconciliations methods were used to ensure all the data (i.e. size & number of files/folders) to ensure all teh data was migrated successfully.

Thanks for your time and effort in advance.
